Abstract (en)

A buck-boost power converting system includes a voltage source input (102) for connecting a voltage source (104) for power conversion. A plurality of switches (S1-S5) are connected electrically to the voltage source input, wherein each switch is connected to a controller configured for control of the switches. A voltage output (108) is configured to connect to a load to power the load with converted power from the voltage source input, wherein the controller is configured to provide positive voltage or negative voltage at a desired level to the voltage output, as needed.
